They stood drooping with the weight of gravity looking toward the rocket in its field of glass and the pink and violet surf beyond. Jan glanced at the bird creatures in the nearest tree. A big cock with green and lavender plumage said, "Coo?" in a definite question.

Jan shook his head unhappily. The bird looked at him for a moment with big lavender eyes, then lifted with easy grace on great wings and flew slowly from tree to tree singing a troubled message.

The Prophet came from the rocket ship. He walked extremely fast considering the gravity. When he reached the group he handed Jan a slip of paper.

"I made these adjustments," he said. "Tell me, won't the ship explode in about half an hour?"

Jan studied the figures on the paper.

"Yes," he said dully.

"You are indeed fortunate," the Prophet said. "I figured it out by studying the microbooks. I had determined from the day we left earth that I would never permit you to leave and spread the alarm. I would have killed you all. But Allah tells us to be merciful. Perhaps I will let you live now."

"We will all die if we don't get out of here fast."

He turned and began to run into the forest. The birds seemed to understand and rose in a swarm from the trees. The crew and the Mohcans followed in sudden panic.
